Sensor bracket

Abstract

A sensor bracket includes a locking wall formed on a bracket main body of the sensor bracket and to which a side surface of the engaging is locked in a pressed state, the side surface of the engaging protrusion being formed so as to cross with a protruding direction of the engaging protrusion; and a biasing piece having a base section and a tip region, the base section being formed so as to be supported by the bracket main body, the tip region being formed so as to abut the side surface of the engaging protrusion and to bias the engaging protrusion in a direction pressing against the locking wall, wherein a plurality of bending deformation sections bent in a state in which the biasing piece is biasing the engaging protrusion against the locking wall are installed between the base section and the tip region of the biasing piece.

What is claimed is: 
     
       1. A sensor bracket that holds a sensor which is attached to an inner surface of a glass windshield of a vehicle, the sensor having an engaging protrusion and a lens section is directed towards the front of the vehicle, the sensor bracket comprising:
 a groove that is formed in a bracket main body of the sensor bracket and through which the engaging protrusion is capable of being inserted in an upward/downward direction, 
 an engaging claw that is formed in a forward side of the bracket main body with respect to the groove and that is configured to lock a front edge portion of the sensor and the sensor bracket, 
 a locking wall that is formed adjacent to the groove on the bracket main body of the sensor bracket and to which a side surface of the engaging protrusion is locked in a pressed state, the side surface of the engaging protrusion being formed so as to cross with a protruding direction of the engaging protrusion; and 
 a biasing piece having a base section and a tip region, the base section being formed so as to be supported by the bracket main body, the tip region being formed so as to abut the side surface of the engaging protrusion and to bias the engaging protrusion in a direction pressing against the locking wall, 
 wherein the sensor is attachable and detachable with respect to the sensor bracket by aligning the engaging protrusion with the groove in the upward/downward direction, 
 wherein a plurality of bending deformation sections bent in a state in which the biasing piece is biasing the engaging protrusion against the locking wall are installed between the base section and the tip region of the biasing piece. 
 
     
     
       2. The sensor bracket according to  claim 1 ,
 wherein the plurality of bending deformation sections comprise at least two bending deformation sections having different bending directions with each other. 
 
     
     
       3. The sensor bracket according to  claim 2 ,
 wherein a folded section curved in substantially a V shape as an initial shape is formed in a deformation region closer to the tip region than to the base section of the biasing piece, 
 a section among the deformation region of the biasing piece near the base section is formed as a first bending deformation section of the biasing piece, and 
 the folded section is made as a second bending deformation section of the biasing piece. 
 
     
     
       4. The sensor bracket according to  claim 3 ,
 wherein the biasing piece is configured as a separate member from the bracket main body, and 
 a support section length of the base section of the biasing piece supported by the bracket main body is set to a length of a half or less than a half of a length obtained by adding the support section length and a length from the first bending deformation section to the second bending deformation section. 
 
     
     
       5. The sensor bracket according to  claim 1 ,
 wherein a folded section curved in substantially a V shape as an initial shape is formed in a deformation region closer to the tip region than to the base section of the biasing piece, 
 a section among the deformation region of the biasing piece near the base section is formed as a first bending deformation section of the biasing piece, and 
 the folded section is made as a second bending deformation section of the biasing piece. 
 
     
     
       6. The sensor bracket according to  claim 5 ,
 wherein the biasing piece is configured as a separate member from the bracket main body, and 
 a support section length of the base section of the biasing piece supported by the bracket main body is set to a length of a half or less than a half of a length obtained by adding the support section length and a length from the first bending deformation section to the second bending deformation section. 
 
     
     
       7. The sensor bracket according to  claim 5 ,
 wherein the bracket main body further including a supporting point part comprises a displacement allowing chamber that accommodates the deformation region closer to the tip region of the biasing piece at more inner side than the base section of the biasing piece and that allows abutting and separating of the engaging protrusion with respect to the locking wall, and 
 at an inner wall of the displacement allowing chamber, the supporting point part, to which the first bending deformation section of the biasing piece abuts and which serves as a deformation supporting point of the first bending deformation section, and a concave section, which allows bending deformation of the biasing piece about the supporting point part, are formed.
